某山区公路路堑滑坡稳定性分析及处治措施研究

The Study on Stability Analysis and Treatment Measures of Cutting Landslide of a Highway in Mountainous Area

山区公路挖方边坡段易出现边坡失稳滑移、塌方等地质灾害,严重危害公路的安全运营。结合某山区高速公路滑坡处治实例,通过勘察调绘分析滑坡原因,并采用传递系数法对滑坡的稳定性进行计算分析,基于计算结果和滑坡体的工程地质特征,综合考虑施工安全和经济合理原则,设计采用圆形抗滑桩进行支挡防护。研究结果对此类工程有一定的借鉴意义。

Geological disasters like slope instability, sliding and collapse easily occur in excavation of highway in mountainous area, which severely impair safe operation of highways. Combined with landslide treatment of an expressway in mountainous area, this paper analyzed the cause of landslide by survey and annotation,conducted computational analysis on landslide stability using transfer coefficient method, and designed circular anti-slide pile for supporting and protection by comprehensively considering construction safety and economic rationality, which could provide certain reference for similar projects.
